02 Overview

2.1 HomeKit Overview

The HomeKit device includes indicators for Power (LED), Energy Consumption (LED), and Communication (LED), a Reset Button, and a USB Port. It also has terminals for connecting power (L1, L2), neutral (N), and CTs (CT1+, CT1-, CT2+, CT2-).

Device Indicators:

• Power LED: Indicates normal status when ON.
• Energy Consumption LED: ON when consuming energy, Blinking when generating energy.
• Communication LED: Blinks twice when trying to connect to the router, blinks four times when trying to connect to the server, ON when transmitting data, OFF if data transmission fails.

03 Installation Instruction

3.1 Installation Environment

• Protection Class: IP20 (for indoor use)
• Operating Temperature: -25°C to +60°C

3.2 Installation (with DIN Track)

1. Pull to release the retaining clip.
2. Mount the HomeKit on the track and push the retaining clip up until it clicks into place, indicating it is installed correctly.

3.3 Wiring Connection

A wiring diagram illustrates the connection of the HomeKit to the SEMS system, router, PV, load, house meter, and grid using CT1 and CT2. The diagram specifies that CT1 connects to the Grid Point and CT2 connects to the Inverter Output Point. The arrow on the CT should point towards the Grid from the Inverter side. RED wires correspond to '+' and BLACK wires correspond to '-'.

Important Notes:

• Please ensure the CT location is correct: CT1 to the Grid Point, CT2 to the Inverter Output Point. The arrow direction on the CT should point to the Grid from the Inverter side. Connection wires: RED for '+' and BLACK for '-'.
• The HomeKit is suitable only for Single-Phase grid applications. Short connect L1 and L2 on the HomeKit side (refer to the wiring diagram) to avoid measurement errors.
